From Santiago Calatrava’s architecture to Ferrán Adriá’s food, Spain reigns as the epicenter of continental cool. Next month, Seville becomes its hot spot. Carmen, fictional Sevillian siren and legendary vixen of opera fame, comes home in a production set to take over the Andalusian town September 2 to 12. Show-goers will stroll between acts progressive-dinner-style to a series of outdoor stages, culminating in the bullring. Oscar-nominated filmmaker Carlos Saura will direct the $16 million Carmen, giving the audience up to two hours between acts to sip sangria and sample tapas. And from September 2 to October 10, the international dance fest Flamenco Biennial takes the stage. Olé!,
